Embodiment
See Fig. 1 and Fig. 2, it illustrates the stereogram of the control valve according to embodiment of the present invention.Wherein illustrate generally control valve with reference character 1, it comprises the tubular part 10 of both ends open, support 20, valve block 30, axle 40, spring 50, lining 60 and beam 70.The structure of each parts of control valve 1 will be specifically described below.
Tubular part 10 according to embodiment of the present invention has circular cross-section, should be appreciated that tubular part 10 also can have rectangle or other shape such as square.In the present embodiment, support 20 is firmly-fixed to the edge of tubular part 10 by welding, but support also otherwise can be fixed to the end of tubular part 10 or joined integrally with tubular part 10.See Fig. 3, support 20 in " U " shape, has substrate 22 and two projections 24 in a top view, that is, support 20 is in the bossed tabular of both sides band.The direction of substrate is parallel to the plane at the edge of opening place of tubular part, and two projections 24 are approximately perpendicular to substrate 22 in the side contrary with side, tubular part place from the two ends of substrate 22 and extend.The lower end of substrate 22 has the shape complementary mutually with the end of the tubular part at place, thus does not cover the opening of tubular part.The upper end of substrate 22 has the groove 23 of the one end for accepting spring 50.Two projections 24 have hole 25 respectively, pass from hole 25 for making axle 40.
See Fig. 4, valve block 30 is pivotally fixed to support 20 by axle 40.Valve block 30 in the sheet with lug, that is, has sheet baffle plate 32 and from two projections 34 that the both upper ends thereof of baffle plate 32 is stretched out, stretches out the side of direction back to tubular part place, and be approximately perpendicular to baffle plate 32 generally.The bottom of baffle plate 32 has the shape corresponding with the shape of tubular part, thus can cover the opening of tubular part completely.The upper end of baffle plate 32 has groove 33, for making one end of spring 50 pass, interferes to avoid spring 50 and baffle plate 32.Distance between two projections 34 is less than the distance between two projections 24 of support 20.Projection 34 forming porose 35 respectively, passing from hole 35 for making axle 40.Can see in Fig. 4, that in the edge of valve block 30---comprising the outward edge of baffle plate 32 and the inward flange in hole 35---has flange, to improve the mode of valve block 30, avoid producing resonance at engine working process middle valve plate 30.The flange of the inside edge in hole 35 forms the flange 36 that the direction along axle 40 extends.In assembled state, the position of groove 33 is corresponding with the position of the groove 23 of support 20, and the position in the hole 25 of the position support 20 in hole 35 is corresponding.
See Fig. 2, axle 40 is through the hole 25 of support 20 and the hole 35 of valve block 30 and be fixed to support 20.Specifically, the first end 42 of axle 40 has flange, the diameter of flange is greater than the diameter in the hole 25 of support 20, thus make flange can be resisted against on the outer surface of projection 24 of support 20, and the second end 44 of axle 40 is firmly-fixed to the opposite side projection 24 of support 20 by modes such as welding, to stop play and the rotation of self of axle 40.By around this axle 40 pivotable, valve block 30 can rotate between the open position making tubular part 10 open and the operating position closed by tubular part 10.
Continue see Fig. 1 and Fig. 2, between support 20 and valve block 30, be provided with elastic element, such as spring 50.Spring 50 is such as be enclosed within the torque spring on axle 50.The first end 52 of spring 50 through the groove 23 of support 20 and the groove 33 of valve block 30, thus is supported by support 20; Second end 54 is resisted against on baffle plate 32, thus applies towards the power of closed position bias to valve block 30.Second end 54 and the projection 35 of spring 50 are positioned at the same side of baffle plate 32.Spring 50 works in high temperature environments, therefore should select high temperature resistant spring, as the spring based on nickel-base material.In addition, although the spring shown in figure is single torsion spring, spring 50 also can be torsion spring or other special-shaped torsion spring, and the groove 23 in this case on support 20 should correspondingly be arranged with the position of the groove 33 on valve block 30.Be to be understood that, elastic element is not limited to the torque spring in present embodiment, but can adopt those skilled in the art thinkable any suitable elastic element apply the power of valve block 30 towards closed position bias, and any suitable arrangement can be adopted.
When valve block 30 is in the close position, the obtuse angle formed between the first end 52 of spring 50 and the second end 54 is greater than the angle that the two is formed under the nature (unassembled state) of spring 50, in other words, now spring 50 is subject to precharge (namely reversing), thus valve block 30 is pressed on tubular part 10, ensure the outlet air tight (see Fig. 6) of tubular part 10.
See Fig. 7, when valve block 30 is opened, the second end of spring 54 moves with valve block 30, the restoring force that spring 50 provides all the time by valve block 30 towards its closed position bias.Specifically, the opening degree of valve block 30 is larger, and the angle between the first end 52 of spring 50 and the second end 54 will be larger, and the restoring force of spring 50 is larger.
Alternatively, between two holes 35 and axle 40 of valve block 30, be respectively arranged with shoe, such as lining 60(is see Fig. 5), this lining is the Steel Wool lining that the stainless steel steel wire being 0.15mm by such as diameter is made, and also can be made up of other suitable material.The main part of lining 60 is snugly assemblied in the hole 35(of valve block 30 in other words, flange 36) in, and there is the center hole for holding axle 40.When valve block 30 overturns, lining 60 will rotate around axle 40 with valve block 30.Lining 60 can be formed with flange 62 in the side near support 20, for the inner side against projection 24, thus positions lining 60 and valve block 30 in the axial direction.Chamfer shape can be had, so that be assembled in the hole 35 of valve block 30 in the side contrary with flange 62 of lining 60.Due to the existence of lining 60 or other shoe, valve block 30 and the contact of axle 40, support 20 can be avoided, prevent valve block 30 and the excessive wear of axle 40, it also avoid fricative noise between these metalworks simultaneously.Should be appreciated that this shoe is not limited to Steel Wool lining 60, but can be any fire resistant wear prevention device that those skilled in the art can be susceptible to, as bearing etc.
Alternatively, the surface that support 20 and valve block 30 are facing is provided with beam 70.This beam 70 is such as made up of stainless steel Steel Wool, can be attached on support 20 and/or on valve block 30, such as, be fixed by spot welding.Obviously this beam 70 also can be made up of other suitable material and otherwise be fixed to support 20 and/or 30.Beam 70 can be such as rectangular.Beam 70 not by compression time thickness slightly larger than the gap between support 20 and valve block 30, be therefore compressible.When valve block 30 turns to operating position by open position, valve block 30 contact tubular part 10 before can first touch beam 70, thus avoid valve block 30 when closed and tubular part 10 clash into the noise produced.
Fig. 8 and Fig. 9 is schematic diagram, show the example in the baffler 2 that control valve 1 according to the present invention is used in the vent systems of motor vehicle, but this is only schematic, should be appreciated that and can be connected with the end of suitable pipeline arbitrary in the vent systems of motor vehicle according to the conduit component 10 of control valve of the present invention.
As shown in the figure, there is multiple chamber separated by dividing plate in the silencing apparatus inside of motor vehicle, for making flow expansion, exhaust is incorporated in the chamber of baffler by exhaust entrance pipeline 3, and there is in baffler the intermediate conduit making to be connected between each chamber, and alternatively there is by-pass line.In the baffler schematic diagram shown in Fig. 8, control valve 1 is arranged on the end of exhaust entrance pipeline 3.Similar in the baffler schematic diagram shown in Fig. 9, control valve 1 is arranged on the end of intermediate conduit 4.Although illustrated thinner by-pass line 5 in Fig. 9, should be appreciated that these figure may not draw in proportion, and control valve 1 also can be arranged on the end of by-pass line.The free end of conduit component 10 can be connected directly to the end of these pipelines, also can be connected to pipe end after enlarging, reducing or distortion.
The working principle of control valve 1 will be described below.For the situation in Fig. 8, control valve 1 is arranged on exhaust entrance pipeline 3.When engine speed improves, the air-flow in exhaust entrance pipeline 3 becomes large gradually, and stream pressure becomes the impacting force being greater than spring 50 and producing, then valve block 30 opens pressure release (see Fig. 7).Open angle along with valve block 30 becomes large, and the windup-degree of spring 50 also becomes large, will produce larger restoring force, and now the maximum, force of spring 50 will depend on the size of the pressure that air-flow produces in tubular part.When tubular part 10 internal gas flow diminishes, valve block 30 gets back to operating position under the effect of spring 50.
For the situation in Fig. 9, control valve 1 is arranged in intermediate conduit 4, and when low engine speeds, air-flow is flowed out by by-pass line 5, and valve block 30 institute is stressed less, is not enough to the impacting force offsetting spring 50 generation, is therefore in closed condition; When rotating speed raises, air-flow has little time to flow out from bypass tube, and the stressed change of valve block 30 is large, and when the pressure that air-flow produces is greater than the power of spring 30 generation, valve block 30 is open, and air-flow is flowed out by intermediate conduit, reaches the effect of pressure release.
Visible, this control valve 1 obtains the backpressure regulation effect of expectation generally by the rigidity of design spring 50.In the four corner of engine speed, closed and the opening degree of valve block 30 changes passively according to the size of air-flow in tubular part 10, thus can the back pressure of regulating system and noise, taken into account motor has excellent acoustic efficiency and engine performance effect under the less slow-speed of revolution of air-flow and the larger high rotating speed of air-flow.
Below introduce the example fabrication method according to control valve of the present invention.First by damping pad 70 by assemble welding to support 20(or valve block 30) on, then by support 20 by the end of assemble welding to tubular part 10.Be tucked into by lining 60 in the hole 35 of valve block 30, the first end 52 of spring 50 is put into support 20 with the corresponding groove 23 and 33 of valve block 30, opposite side 54 is against valve block 30.By the second end 44 of axle 40 successively through the hole 25 of the hole 25 of side of support 20, side lining 60, spring 50, opposite side lining 60 and support 20 opposite side, and the second end 44 is soldered to support 20.It will be appreciated by those skilled in the art that can adjust above step according to specific needs order, deletion or increase manufacturing step.
Below be only illustrative embodiments of the present invention, by reference to the accompanying drawings and after specification, those skilled in the art easily can make multiple transformation to the present invention, and all these transformations all fall in the scope of claims.
